Flexwatt was never really designed for the reptile industry...we adopted it and it worked and has for many, many years. THG was degined with the reptile hoppy in mind. With over 3 years of testing in research, it is just made better and has better uniform heat output. I currently use Flexwatt under all my enclosures but will be swapping it out for THG here very soon.
